The orifice is set at the base of the tank through a special wall fitting that provides a flush inside surface. In the Orifice and Free Jet Flow accessory a constant head tank is fed with water from the Hydraulics Bench. A jet trajectory tracing device allows the path followed by the jet to be ascertained. The head is maintained at a constant value by an adjustable overflow and is indicated by a level scale.

The Flowmeter Measurement Apparatus consists of a Venturi meter, variable area meter and orifice plate, installed in a series configuration to permit direct comparison. Pressure tappings are incorporated so that the head loss characteristics of each flow meter may be measured. Pressurisation of the manometers is facilitated by a hand pump. These tappings are connected to an eight tube manometer bank incorporating a manifold with air bleed valve. A flow control valve permits variation of the flow rate through the circuit.
The bench is used as the source of water supply and for calibrating volumetrically each flow meter. The circuit and manometer are attached to a support framework which stands on the working top of the Hydraulics Bench.
Boundary layer growth is determined by the measurement of the velocity profile at four stations along the pipe using a traversing Pitot tube.
A bend or mitred cascade elbow may be fitted mid way along the smooth wall pipe for comparison of pressure losses.
Air enters the smooth walled pipe through one of the two flow measurement nozzles provided. Pressure tappings along the length of the pipe permit the pressure gradient to be determined.
The equipment includes a long smooth walled pipe joined to the suction side of an electrically operated centrifugal fan. The fan discharge pipe terminates in a flow control damper for closed conduit work or a plate containing a small aperture for jet dispersion measurements.
A conventional flow measuring orifice plate is supplied for installing in the pipe upstream of the fan for additional demonstrations of pressure loss and recovery.
The equipment is mounted on a floor standing steel frame with an adjacent support for the extended suction pipe. Pressure measurements are made on a multi-tube inclinable manometer mounted on the support frame.
Air jet studies are carried out on the discharge side of the fan. A Pitot tube is traversed vertically and horizontally at different distances from the discharge orifice to investigate the dispersion properties.

The Flow Channel made up of a clear acrylic working section of large depth to width ratio incorporating undershot and overshot weirs at the inlet and discharge ends respectively.
Models supplied with the channel include broad and sharp crested weirs, large & small diameter cylinders and symmetrical & asymmetrical aerofoils which, in conjunction with the inlet and discharge weirs, permit a varied range of open channel and flow visualisation demonstrations.
A dye injection system incorporated at the inlet to the channel permits flow visualisation in conjunction with a graticule on the rear face of the channel.
Water is fed to the streamlined channel entry via a stilling tank to reduce turbulence. Water discharging from the channel is collected in the volumetric tank of the Hydraulics Bench and returned to the sump for recirculation.
The Flow Over Weirs is a kit containing two types of sharp crested weirs and a level gauge. The weirs have opening or sections at the top that allow flow; the Thomson weir with V-profile opening, the weir with rectangular profile opening. A sharp crested weir constricts an open channel flow, and helps in measuring flow rate using level gauge contained within the set.
The Flow over Weirs consists of five basic elements used in conjunction with the flow channel in the moulded bench top of the hydraulics bench.
A Vernier hook and point gauge is mounted on an instrument carrier, which is located on the side channels of the moulded top. The carrier may be moved along the channels to the required measurement position.
A quick release connector in the base of the channel is unscrewed and a delivery nozzle screwed in its place.
A stilling baffle locates into slots in the walls of the channel. The inlet nozzle and stilling baffle in combination promote smooth flow conditions in the channel.
The rectangular notch weir or Vee notch weir to be tested is clamped to the weir carrier in the channel by thumb nuts. The weir plates incorporate captive studs to aid assembly.
Many parts have been chromium-plated and galvanized for a longer life. Air Flow Sensor Cutaway is carefully sectioned for training purposes, professionally painted with different colours to better differentiate the various parts and cross-sections.
